Active clinical trials for "Urinary Bladder Neoplasms"

Introduction Bladder cancer is the most common malignancy involving the urinary system and the ninth most common malignancy worldwide. Urothelial carcinoma is accounts for approximately 90 percent of bladder cancers in the western world. In the United States, approximately 80,000 new cases and 17,000 deaths occur each year due to bladder cancer. Approximately 75% of patients present with superficial disease (Ta and T1), while 25% present with muscle invasive (T2 or greater) disease. Overall, 70% of treated tumors recur, with 30% of recurrent tumors progressing to muscle invasive disease. The majority of these patients have a recurrence after endoscopic resection, thus lifelong surveillance with periodically cystoscopy is recommended. Cystoscopy, which is the "gold standard" for the detection of bladder cancer, is an expensive and invasive procedure, and it also can miss a flat lesion, especially carcinoma in situ which is considered a high grade malignant condition, therefore better follow-up tools should be developed in order to address those issues. Voided urinary cytology is a useful noninvasive adjunct to cystoscopy due to its high specificity, more than 90%. Although it has a high sensitivity at detecting high-grade lesions, between 80 to 90%,, in low-grade its sensitivity is very low, between 20 to 50%. Amongst the non-muscle-invasive, low grade tumors will progress to muscle-invasive or metastatic cancer at approximately 10% and roughly a third of high-grade tumors progress, therefore, close monitoring and early detection of all lesions are important for management, and noninvasive tumor markers with high accuracy for the detection of all grades of urothelial carcinoma will significantly reduce patient cost, anxiety and morbidity. Cystoscopy in combination with cytology remains the most effective means of detecting bladder cancer. However, cystoscopy is an invasive procedure, and while cytology remains a useful method for detecting high grade tumors, its utility in detecting low grade tumors remains limited due to the lack of distinguishing cytological features between low grade disease and reactive processes. Currently there are several markers available or under investigation for the detection and monitoring/surveillance of bladder cancer, most of them have higher sensitivities, especially when used to identify low grade disease, but with lower specificities when compared to cytology. Furthermore, all of these tests must still be utilized in conjunction with cystoscopy findings. Recently, cell-free DNA (cfDNA) isolated from urine supernatant has been shown to have great potential in bladder cancer detection and surveillance. Bladder cancer exhibits unique genetic features that can be identified from sequencing and expression of cfDNA. Aim of study: The aim of this study is to establish a method for a personalized urinary biomarker with the usage of well explored urothelail cancer genetic mutations in urine cfDNA, for the detection of bladder cancer presence.

The purpose of this research is to determine whether bladder cancer monitoring can be improved by replacing some cystoscopy procedures with urine testing. Specifically, this study examines whether there are any differences in urinary symptoms, discomfort, number of invasive procedures, anxiety, complications, cancer recurrence or cancer progression when some cystoscopy procedures are replaced with urine testing.

This is a multi-center study and the aim is to develop and validate an Artificial Intelligence (AI) -based histologic analysis tool to predict responsiveness to intravesical Bacillus Calmette-Guérin (BCG) and intravesical chemotherapy in intermediate and high-risk non-muscle invasive bladder cancer patients.

The purpose of the trial is to establish the tolerability of tisotumab vedotin (HuMax-TF-ADC) dosed three times every four weeks (3q4wk) in a mixed population of patients with specified solid tumors.

A Phase II, Multi-Center, Open-Label Study of Tremelimumab Monotherapy in Patients with Advanced Solid Tumors

This study aim to compare the efficacy, safety and quality of life of vinflunine/gemcitabine and carboplatin/gemcitabine in patients with metastatic urothelial cancer and impaired renal function.

Previous multi-dose Phase I and Phase II clinical studies have demonstrated that ADSTILADRIN is a safe and effective treatment for BCG-refractory and recurrent NMIBC. This Phase III study is designed to expand those observations using a high dose of ADSTILADRIN in patients that are "BCG Unresponsive" which refers to patients with high-grade NMIBC who are unlikely to benefit from and should not receive further intravesical BCG.

The purpose of this study is to determine if TAR-200, an investigational drug-delivery system, is safe and tolerable in patients with muscle-invasive bladder cancer (MIBC) between diagnosis and radical cystectomy (RC).

A prospective, open label, modified 3+3 dose escalation study. This dose-escalation study is designed to carefully assess the safety of successive cohorts of patients (3 patients/cohort), each cohort treated with a fixed dose of TC-3 and MMC Intravesical instillations.

This is a randomized, open-label Phase 2 clinical trial to evaluate whether suppression of Hsp27 (Heat shock protein 27) production using OGX-427, a second-generation antisense oligonucleotide (ASO), in combination with docetaxel can prolong survival time compared to docetaxel alone in participants with locally advanced or metastatic urothelial carcinoma (UC) that are relapsed or refractory after receiving a platinum-containing regimen.
